BY am Patented June 13, 1950 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to improvements in del vices for holding, feedingand closing or crimping hog hooks or rings.

The principal features of the invention are directed to the provision ofa device for holding a supply of hog hooks or rings which may beinserted in various materials and for crimping the same and ischaracterized by a supply of hog hooks which are held together forseparation by the device.

Hog hooks or rings, hereinafter called staples, are used for many andvarious purposes such as for instance to secure adjacent edges ofautomobile seat covers together. These staples are generally U-shapedhaving side legs which are inserted through fabric, leather or the likeand when so disposed the legs are brought together or into overlappingrelation to provide a ringlike securing member.

The device comprises a novel combination and arrangement of partsadapted whereby a stack of staples may be inserted therein and theendmost staple held between relatively movable jaws in such a way thatthe legs thereof may be inserted in material. The operation is such thatthe endmost staple is crimped and closed and a successive staple broughtinto position.

To facilitate efilcient operation the staples are arranged in the formof a stack and are releasably held together so as to be manipulatable asa unit while at the same time successive staples may be separated fromthe end of the stack by the device. To enhance efliciency and utilitythe staples in the form of a stack are arranged angularly relatively tothe direction of their feeding movement.

With the foregoing and various other novel features and advantages andother objects of my invention as will become more apparent as thedescription proceeds, the invention consists in certain novel featuresof construction and in the combination and arrangement of parts as willbe hereinafter more particularly pointed out in the claims hereuntoannexed and more fully described and referred to in connection with theaccompanying drawings wherein:

Fig. 13 is a perspective view at the forward end of the device withparts broken away for clearness.

Referring now to the drawings more in detail, the invention will befully described.

A housing 2 is provided which is adapted for use as a handle. Preferablythis is in the form of an inverted U as shown in sections in Figs. 6 to9 inclusive.

The forward end 4 of the housing is enlarged, as shown in Figs. 2, 4,and 5. A lower wall 6 extends longitudinally of the housing and issecured thereto.

A cap 8 is removably secured to the rear end of the housing in anysuitable manner and a longitudinal rod l0 projects through the rear sidethereof and has a manually engageable member l2 fixed thereto.

A longitudinal guideway is formed on the wall 6 by longitudinal sidemembers [4 which extend upwardly from said wall, see Fig. 6.

The rod H1 is screw threaded in a boss It at the forward end of the wall6, see Fig. 5, and may be readily connected to and released therefrom. Afollower i8 is slidable on rod I0 and it has an inclined forward face orside as shown in Fig. 11.

A stack 20 of staples 22 is slidable along the guideway formed bymembers [4 and is urged forwardly by follower l3 which is acted upon bya, spring 24 around rod H). The endmost or outermost staple abuts theinner side of jaw members 26 and 28.

The staples are releasably secured by some readily rupturable materialsuch as wax, solder or the like and they are arranged in the inclinedrelation shown so as to be projected angularly.

According to the invention the means securing the staples in stackedrelation will be such that the outermost or endmost staple may bereadily removed from the stack. In loading the device the cap 8 isremoved from the housing and the rod is unscrewed from the boss l6 sothat a stack of staples may be placed in the guideway forwardly of thefollower.

An operating lever 3|] is pivoted at 32 to the housing and it is urgedin a clockwise direction by a compression spring 34 having one end 35disposed in a boss 36 and its other end 31 bearing on the inner side oflever 30.

The lever 30 at one side has a curved cam face 38 which works in aconcavity 40 of a segment 42 that is pivoted at 44 for oscillations backand. forth. Below cam face 38 the lever 30 is provided with teeth 45 formeshing with teeth 48 of segment 42.

A head 55 is secured to the forward end of the housing and a slide 52 isslidable up and down therein. The parts are arranged so that the slidemoves on an incline or at an angle relative to a plane at right angle tothe longitudinal axis of the housing. The jaw 28 is integral with head50 and jaw 28 is pivoted thereto at 54.

A plate 55 is secured to the forward face of the head and. it has offsetportions 58 in which a shaft 50 is journalled. Said shaft carries gears62 and 64 and said gear 62 meshes with slots 6 in slide 52 while gear 64meshes with teeth 65 of segment 42.

Jaw 28 is urged towards jaw 26 by a spring which has one end 'liiconnected thereto and its other end 12 connected to plate 56, see Fig.3. Inner sides of jaws 25 and 2-8 are provided with slots 14 forreceiving and guiding staples when pushed thereinto by slide 52.

A shaft 85 is journalled at the forward end of the housing on an axisparallel to that of rod [-0. Opposite ends 82 and 84 of said shaft areoffset as shown in Fig. 12. Shaft end 84 engages a bracket 86 secured tojaw 28 and end 82 is disposed below and acted upon by a cam part 88 onthe forward end of lever 30. It will be explained that lever 30 ischannel-shaped and at its forward or outer end has cam part 38 and campart 88 in spaced relation at opposite sides of the guideway for thestaples.

As shown, a staple 22 is held between the jaws 2G and 2B. The housingwhich functions as a handle may be grasped in an ordinary manner and thestaple may be inserted in material such as fabric or the like.

With the staple inserted in the material, lever 3!! is movedcounterclockwise as by squeezing the lever and handle. This movement oflever '30, which is against action of spring 34, causes cam part 88 ofthe lever to act on part 82 of shaft 80 so that part 34 of said shaftswings jaw 28 towards jaw 28. The jaws in being closed crimp or closethe staples as shown in Fig. 10. During this movement a lever 30 theconvex end portion 38 thereof slides on surface 40 of segment 42.

Subsequent to crimping of the staple the lever is re eased and is swungclockwise by spring -34 and teeth 45 of the lever engage teeth 48 ofsegmcnt so that it is swung counterclockwise. In this movement ofsegment the teeth 55 thereof in engagement with gear 64 and with gear 62engaging slots 66 of slide 52 causes the slide to move downwardly so asto remove the endmost staple of the stack and push it into and betweenjaws26 and 23 so that it is in the position shown.

The invention may be embodied in other specific forms withmit departingfrom the essential characteristics thereof. Hence, the presentemboriiments are therefore to be considered in all respects merely asbeing illustrative and not as being restrictive, the scope of theinvention being indicated by the appended claims rather than by theforegoing description, and all modifications and variations as fallwithin the meaning and purview and range of equivalency of the appendedclaims are therefore intended to be embraced therein.
